Optical tactile sensors are extensively utilized in intelligent robot manipulation due to their ability to acquire high-resolution tactile information at a lower cost. However, achieving adequate ...

There must be no chemical reaction between the sensor material and the sample. Use a sensor with a low cell constant (0.01 to 0.1 cm-1) for low conductivity measurements and a sensor with a higher ...

Traditional medical tests often require clinical samples to be sent off-site for analysis in a time-intensive and expensive ...

Recently, novel fluorescent probes based on biomaterials and luminescent nanomaterials for metal ions attract tremendous attentions, owing to their advantages of simple operation, high sensitivity and ...

High time-resolution monitoring of nitrogen dioxide (NO 2) is of great importance for studying the formation mechanism of aerosols and improving air quality. Based on the Griess–Saltzman (GS) reaction ...

Over the last decade, portable, active optical sensors (AOS) have become tools in production agriculture both for mapping crops and soils and also for applying agrochemicals. These sensors are often ...

We report the specific detection of a few hundred molecules of genetic material using a fluorescent polythiophene biosensor. Such recognition is based on simple electrostatic interactions between a ...
